I've been taking Vitamin D, C, Zinc and Green Tea Extract or Macha Tea from the outbreak of Covid. Does it prevent infection? Not sure and don't really care if it does. It sure as heck doesn't hurt. I am vaxed but got it late just because I'm not in a super high risk group and it's LA which has it's own issues.
My main issue is that my confidence in the Pharma and medical industry has been shaken to it's core. I had great faith in the medical establishment before this "Pandemic" It has been so politicized and compromised I'm not really sure how they climb back to credibility. The nail in the coffin was definitely the gaslighting and politicization of HCQ during Trump. More specifically the retraction of articles and research by the "Lancet" and the "New England Journal of Medicine" which scrubbed previous articles, research and discussion about HCQ along with supplements as a prophylactic or mitigation regimen for Sars/Covid back in 2005. Along with bogus articles about heart complications with using these drugs it was clearly politically motivated. Interesting that after the big headlines and intended effect these articles were redacted and scrubbed. Even from an anecdotal perspective I've had extensive experience with antimalarial drugs because I've been in so many sh$%hole countries and have found these long used and studied drugs to be anything but dangerous.
Sorry, there are so many things about this "Pandemic" that don't pass the smell test that I've basically given up trying to understand what might or might not be correct information. I'm vaxed, take vitamins and zinc, wear a mask because the idiots in LA require it but I'm pretty much done with getting more boosters and definitely not down with going to restaurants or venues that require a yellow star on my shoulder for entry permission.
